*Really looking forward to the new release of this, i use reminders extensively not really as reminders but more as long term data store so I have race PBs and pace info on hand.
I have separate lists for parkrun, 10k, 10mile, half, marathon, trail, ultra, track etc...and each list contains PB time and pace of each event I’ve ever ran...and the parkrun list includes a count of each parkrun plus at the top level an overall count, so I know when I’m about to hit any milestones (I’m on 180 parkruns across 11 venues at the moment).
And then I manually sort each list so in my 10k list for example I’ve got the sixteen separate 10k races I’ve ran (most of which I’ve done multiple times), listed with my actual 10k PB course top of the list, and then gradually dropping down through the slower ones.
So if I go into a race on good form and a course best is possible, part of my pre race routine is to look in reminders for my previous best at that event, grab the pace, and enter that as a target pace in Workoutdoors...all whilst my phone is back in the car out of range.
